Unconventional Completions—Wellbore Completions and Fracturing

Drilling and Completions Production and Operations


This course develops strategies for completing unconventional wells that require multistage hydraulic fracturing. This course defines completions as both the wellbore completion and they hydraulic fracturing. Participants will learn the different types of wellbore completion options as well as the hydraulic fracturing options and how they compare in different applications. This will include plug-and-perf, ball-activated systems, coiled tubing-activated systems, fracturing fluids, proppants, additives, and general fracturing theory and design.

Topics include:

  • Wellbore completion options for unconventional reservoirs
  • Wellbore completion comparison for unconventional reservoirs
  • Application specific solutions for wellbore completion design
  • General fracturing theory and design
  • Selection of fracturing components – fluids, proppants, etc.
  • Fracturing challenges – proppant transport, conductivity, frac geometry, etc.

At the end of this course, participants will be able to:

  • Know the benefits and considerations for each type of wellbore completions
  • Recognize that certain completions have made benefits in some applications
  • Understand the purpose of a fracturing job
  • Identify the application specific challenges for a fracturing job
  • Account for the challenges in the fracturing design

Learning Level

Introductory to Intermediate

Course Length

1 Day

Why Attend?

In the last seven years the oil and gas industry has seen significant changes in the price and supply of hydrocarbons, primarily due to new production from low-permeability unconventional reservoirs that require multistage hydraulic fracturing. As a drilling, completion, or reservoir engineer, it is important for you to understand the many options and challenges of completing these types of wells.

Who Should Attend

This course is designed for drilling, completion, and reservoir engineers, and for service company personnel involved with planning, drilling, completing and operating well with multistage hydraulic fracturing. Engineers involved in designing wellbore completions and fracturing engineers wanting to learn about wellbore completions.

Aaron Burton is the business development manager for Unconventional Completions, a group primarily focused on the completion of shales and similar unconventional plays that require multistage hydraulic fracturing. Burton joined Baker Hughes as a field engineer trainee for completion tools after graduation. During his tenure in operations, he has held the roles of field engineer, operations coordinator, and district engineer. He has completed wells in several unconventional plays in North America, including the Bakken, Marcellus, and the Lower Huron.

Burton holds a BS in mechanical engineering from Mississippi State University.

Sergey Kotov is the manager of the simulation, unconventional resources team, global marketing at Baker Hughes.  He has over 17 years’ experience in stimulation of oil and gas reservoirs.

Kotov started with Canadian Fracmaster as a well stimulation department interpreter in 1995.  After the acquisition of the company by BJ Services in 1999, he developed his career as a filed stimulation/cementing engineer.

Kotov designed and implemented hydraulic fracture treatments in all major oil and gas fields in Russia from the South of the Arctic Circle.  As an application engineer of BJ Services Technology Research Center, he participated in the development and optimization of new stimulation technologies and implemented field trials in the US.  He also provided technology transfer both domestically and internationally.

As a senior stimulation specialist, Kotov provided engineering support to BJ Services operations in North Africa (fracturing, acidizing, water control, and etc.).  He developed the stimulation strategy for several fields in Algeria and Libya.

Kotov holds an MS in petroleum engineering from North Caucasus State Technical University in Stavropol, Russia and an MA in linguistics from State Linguistic University, Pyatigorsk, Russia.
